We look at the division of 408218 by 90 
We want to divide 408218 by 90.

Advancing to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 90

Step 2:
The number 90 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 90

Moving on to step 3:
90 can be fit into 408 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 360 from 408 leaves us with 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 90

On to step 4:
90 goes into 482 5 times with a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 32 after subtracting 450 from 482.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 90

Going ahead to step 5:
321 divided by 90 is 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 453.0
Subtract 270 from 321 to get 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 90

On to step 6:
When dividing 518 by 90, we get 5 with a remainder of 68.
Record the quotient 5 as the next digit in the result. 
Result so far: 4535.0
Subtracting 450 from 518 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 7:
90 goes into 680 7 times with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 4535.7
Subtracting 630 from 680 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 4535.75
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 4535.755
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 4535.755 with a remaining 0.005.
